The components are cooperated with each other, so that the lubricating oil has good lubricating applicability to the turbine and the worm on the whole. Generally, sulfur-containing extreme pressure agents in gear oil are low in cost and vulcanized olefin is selected, but the vulcanized olefin is poor in lubricating effect and is easy to convert into active sulfur at high temperature, so that corrosion is caused to copper parts. Meanwhile, the worm gear used in the harsh working environment is easy to vibrate, and the worm gear lubricating oil is required to have higher lubricity than the conventional industrial gear oil. The used sulfurized fatty glyceride has good lubricity and a certain extreme pressure effect, the content of active sulfur is less than 1wt%, the influence on copper is small, the viscosity at 40 ℃ is 200-800 mm2/s, and the sulfurized fatty glyceride has good lubricating property and good solubility. The polyether is selected as the base oil, and the mineral oil and the PAO oil used by the gear oil have better water diversion effect than the base oil, and meanwhile, the lubricity of the polyether can reach the lubricity of the ester oil, but the polyether is better than the ester oil in the aspect of cooperativity with the antioxidant. Through the selection, the obtained lubricating oil has strong applicability to the turbine and the worm, has good lubricity, extreme pressure property, water separation property and oxidation resistance, and can effectively reduce the abrasion between the turbine and the worm. And the preparation method of the lubricating oil is simple and pollution-free, and the cleaning grade of the lubricating oil reaches 6-7 grade by filtering with the filter bag twice.
The invention has the following beneficial effects:
the lubricating oil disclosed by the invention is strong in applicability to a turbine and a worm, has good lubricity, extreme pressure property, water separation property and oxidation resistance, can effectively reduce abrasion between the turbine and the worm, is simple in preparation method and free of pollution, and the cleaning grade of the lubricating oil reaches 6-7 grades through twice filtration of filter bags.
